ALM Squarp Rample (2019–2023)

A no-nonsense, four-channel Eurorack sampler that plays back full-length .wav files with surgical precision and zero pretense—no recording, no frills, just raw sample muscle.

Overview

Plug in a microSD card loaded with your favorite drum hits, field recordings, or hour-long ambient drones, and the Rample doesn’t flinch. It’s not trying to be a synth, a looper, or a compositional suite—it’s a playback engine built for modular rigors, and it does that one thing exceptionally well. You can hear the design philosophy the moment you patch it: four independent stereo channels, each with dedicated trigger, CV, and gate inputs, letting you mangle, sequence, and layer samples with surgical control. There’s no internal recording, no touchscreen wizardry—just a small dot-matrix display that shows you exactly what you need, nothing more. It feels like a tool, not a toy.

Launched in 2019 and developed by ALM (a collaboration between Andrew M. and Squarp Instruments), the Rample emerged during a golden era of Eurorack sampling, when modules like the Erica Synths Sample Drum and ALM’s own Squid Salmple were redefining how samples lived inside modular systems. But where others leaned into recording or effects, the Rample went the opposite direction: pure, high-fidelity playback with maximum flexibility in how you trigger and modulate. It’s the kind of module you reach for when you want to drop in a perfectly timed snare, a glitchy vocal snippet, or a cinematic swell without wading through menus or worrying about sample time limits.

And about those limits: there aren’t any. Seriously. You can load a 45-minute ambient piece onto one channel if you want. The only constraint is your microSD card’s capacity and your willingness to organize folders named A00 to Z99—2600 total kits, each holding up to 12 samples per channel. That’s not just overkill; it’s a statement. This isn’t a drum machine pretending to be a sampler. It’s a sampler that can *do* drums, but also drones, soundscapes, spoken word, or even full backing tracks. Want to randomize between four kick samples on a single channel based on velocity? Done. Want to sweep pitch across 10 octaves via CV? The Rample handles it with a cold, digital precision that feels almost unfair in a world of wobbly analog oscillators.

But let’s be clear: this isn’t a module for beginners. There’s no screen to guide you, no undo button, no visual feedback beyond the minimal display. You’ll be navigating kits and samples via button presses and LED blinks, and if you’re not comfortable with that, look elsewhere. It rewards organization—naming your samples logically, grouping them in folders, knowing what’s in A23 versus B07. But once you’re set up, it’s lightning-fast in performance. No loading screens, no stuttering, no buffer issues. Just trigger, and it fires.

It’s also not trying to be warm or lo-fi. The audio output is clean, transparent, and digital—some might say sterile, but that’s the point. It’s a canvas. Want grit? Run it through a distortion module. Want movement? Patch in an LFO to the pitch CV. The Rample gives you the raw material and gets out of the way.

Key Features

No Sample Length Limits—None

In a world where most Eurorack samplers cap you at a few seconds or force you into one-shot territory, the Rample’s refusal to impose any time restriction is quietly revolutionary. You’re not just limited to drum hits or stabs. Load a full ambient composition, a spoken word poem, or a field recording of a rainstorm onto a single channel and trigger it like any other sample. This makes the Rample uniquely suited for live performance or installation work where long-form playback is essential. The only bottleneck is your SD card and file management—there’s no internal memory or buffer constraints. It reads directly from the card, so as long as the file is there, it plays.

Per-Channel CV Over 10 Octaves

Each channel accepts a CV input that can sweep pitch from –5V to +5V, translating to a full 10-octave range. You can use this in linear mode for smooth, non-musical sweeps, or switch to V/octave for chromatic tracking. This is where the Rample stops being a simple sample player and starts feeling like a synth voice. Want to play a multisampled kick across a keyboard? Assign MIDI notes via CV and let the Rample respond like a ROMpler. Want to drop a sample down three octaves with a simple offset? Patch in a negative voltage. The control is immediate, precise, and deeply integrated into the modular workflow.

Randomization and Velocity Mapping

One of the Rample’s most underappreciated features is its ability to randomize playback between multiple samples on a single channel. You can load up to 12 variations of a kick, snare, or synth stab and have the module choose which one fires based on incoming velocity, MIDI CC, or even random chance. This brings organic variation to otherwise static samples—no two hits need sound the same. For drum programming, this is gold. For sound design, it opens up generative possibilities without needing external logic modules. It’s not full-on granular synthesis, but it’s a clever workaround that gives the illusion of complexity with minimal patching.

Historical Context

The Rample arrived in 2019, a time when Eurorack was embracing more complex digital modules, but sampling was still a niche pursuit. Most samplers either focused on short-looping (like the Make Noise Morphagene) or were tied to specific workflows (like the Mutable Instruments Clouds, which leaned heavily into granular textures). The Rample stood apart by treating samples like instruments—something to be triggered, tuned, and performed, not processed into oblivion. It shared DNA with the Squid Salmple, another ALM/Squarp collaboration, but where the Salmple emphasized recording and internal sequencing, the Rample was all about playback fidelity and routing flexibility.

It competed most directly with the Erica Synths Sample Drum, a two-channel sampler with onboard recording and effects. The Sample Drum offered more per-channel features but only two channels and a more menu-heavy interface. The Rample, in contrast, offered four channels, no recording, and a more immediate, performance-oriented workflow. The choice between them often came down to workflow preference: do you want to record and edit inside the module, or import and play with maximum routing freedom?

Firmware updates kept the Rample relevant throughout its production run, adding features like improved MIDI implementation and better folder navigation. But it never tried to be everything. It stayed focused—so focused that when ALM eventually shifted attention to newer platforms like the SQ-1 and Squid, the Rample quietly faded out of production by 2023. It wasn’t replaced; it was simply retired, leaving behind a loyal user base that still swears by its reliability and simplicity.

Collectibility & Value

As of 2026, the Rample trades between $350 and $450 on the used market, depending on condition and whether it includes the original microSD card and documentation. Units sold with a pre-loaded card of high-quality samples—especially drum kits or curated sound design packs—often fetch closer to the upper end. There are no known hardware revisions, so all units are functionally identical, but firmware version matters: anything below v1.5 may lack newer MIDI features, so buyers should verify the version before purchasing.

The most common failure points are mechanical: the microSD card slot can wear out with frequent swapping, and the front-panel buttons, while sturdy, can develop contact issues after years of heavy use. There are no user-serviceable fuses or internal batteries, so failures usually require board-level repair. However, the module is generally robust—no overheating issues, no known capacitor plague, and minimal power draw. It’s not prone to crashing, and firmware updates are stable.

When buying, test all four channels for audio output, verify that CV pitch control responds smoothly across the full range, and check that the display updates correctly when changing kits. Make sure the microSD card is recognized and that sample loading works—some users report issues with cards formatted as exFAT or over 32 GB, so stick to 16–32 GB FAT32 cards for compatibility.

Because it doesn’t record, the Rample isn’t a standalone solution. It’s best paired with a DAW or computer for sample preparation. This limits its appeal to purely modular purists, but for those who already work hybrid, it’s a dream. It’s also a favorite in live rigs where reliability and speed matter more than onboard creativity.
